MIRI Imaging Target Acquisition

See also: JWST Pointing Performance

Target acquisition (TA) is generally not required for MIRI imaging observations, as the blind pointing ability of the telescope is sufficiently accurate to center the target in the imager field or subarray. Early experience with imaging time-series observations have found that even for multi-epoch TSO programs, the pointing accuracy does not limit the spectrophotometric precision. TA is therefore not supported for MIRI imaging or time-series imaging.
